Description

Technical Field

[0001] This utility model belongs to the technical field of crushing devices, specifically relating to a crushing device for edible fungi cultivation raw materials. Background Technology

[0002] The raw materials for edible fungi cultivation are mostly made by crushing and mixing sawdust, wheat bran, straw, etc., and then adding an appropriate amount of nutrient solution. After the fungi are planted in these mixed raw materials, they can grow rapidly and fully absorb nutrients to increase their growth rate. Sawdust accounts for a relatively high proportion of the raw materials used for edible fungi cultivation. Among them, sawdust from decaying wood is the most effective for cultivating edible fungi. Therefore, growers need to prepare a large amount of wood to be crushed into sawdust when cultivating edible fungi. Existing sawdust crushers are expensive and mainly use saw blades to crush wood. The resulting sawdust is very fine and cannot retain moisture. On the contrary, larger sawdust particles are more suitable for fungal growth. Utility Model Content

[0003] In order to overcome the problems in the background art, this utility model provides a crushing device for edible fungi cultivation raw materials.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1 to 6 This utility model discloses a raw material crushing device for edible fungi cultivation, comprising: a frame 1, an outer cover 2, and crushing rollers 3. A conveyor belt 11 is installed on the frame 1, and a long strip 111 is provided on the conveyor belt 11. The outer cover 2 is installed on both sides of the frame 1. Three crushing rollers 3 are provided inside the outer cover 2. The crushing rollers 3 are rotatably mounted on the outer cover 2 on both sides. The crushing roller 3 located on the front side of the outer cover 2 is close to the top of the outer cover 2, the crushing roller 3 located near the front side is located in the middle position, and the crushing roller 3 located on the rear side is close to the conveyor belt 11. The distance between each crushing roller 3 is the same. A filter plate 23 is installed at the rear end of the outer cover 2, and a discharge port 5 is provided on the rear side of the filter plate 23.

[0022] It should be noted that, for reference Figure 1 , Figure 3 , Figure 5 As shown, the crushing zone of this device is mainly located inside the outer casing 2. The wood is cut into wood chips by the rotation of the crushing drum 3. The filter plate 23 is used to block the moving wood and prevent the wood from moving to the rear side before being cut. The wood chips fly out from the mesh of the filter plate 23 and are discharged from the device through the discharge port 5. When the wood chips are cut, they gain a lot of kinetic energy, so they can easily pass through the filter plate 23. The conveyor belt 11 is used to move the wood. The long strips 111 on the conveyor belt 11 can hold the wood and pull the wood into the device. The long strips 111 can reduce the contact area between the wood and the conveyor belt 11, thereby increasing the friction and making the wood more stable during the movement.

[0023] In this embodiment, the crushing roller 3 has circular grooves 32 on both sides, and the inner wall of the outer cover 2 has a sleeve 24 that matches the grooves 32. The grooves 32 are rotatably installed in the middle of the sleeve 24.

[0024] In this embodiment, steel bars 31 are uniformly arranged on the crushing drum 3, and crushing teeth 311 are linearly formed on the steel bars 31.

[0025] It should be noted that, for reference Figure 5 , Figure 6 As shown, the crushing roller 3 must be fixed during installation to prevent it from falling off during subsequent use and colliding with each other, which could cause a serious accident. If the crushing rollers 3 collide with each other, the evenly distributed steel bars 31 on the crushing rollers 3 may break and fly out of the device, injuring people working outside. Therefore, when installing the crushing rollers 3, after installing them at both ends, the sleeves 24 need to be fitted onto the grooves 32 to prevent the crushing rollers 3 from swinging left and right. The sleeves 24 need to be welded to the outer cover 2 so that the entire crushing roller 3 cannot fall off, thus improving the safety of the device.

[0026] In this embodiment, a through hole 22 is provided on one side of the sleeve 24, and a rotating shaft 33 is provided on the side of the crushing roller 3 and passes through the through hole 22. A pulley group 4 is installed at the other end of the rotating shaft 33. The pulley group 4 is divided into a first pulley 41, a second pulley 42, and a third pulley 43. The crushing roller 3 on the front side of the outer cover 2 is connected to the first pulley 41, the crushing roller 3 in the middle position is connected to the second pulley 42, and the crushing roller 3 on the rear side is connected to the third pulley 43. The first pulley 41 and the second pulley 42, as well as the second pulley 42 and the third pulley 43, are respectively connected by belts. At the same time, a crushing motor 401 is provided below the third pulley 43, and a belt is also provided to connect the third pulley 43 and the crushing motor 401.

[0027] It should be noted that, for reference Figure 3 , Figure 4 As shown, the cutting of this device is mainly carried out by the crushing drum 3. The crushing teeth 311 on the steel bar 31 cut the wood into wood chips. The power of the crushing drum 3 is mainly provided by the crushing motor 401. The crushing motor 401 drives the third pulley 43 to rotate, which in turn drives the crushing drum 3 at the rear to rotate at high speed. The second pulley 42 is connected to the third pulley 43 by a belt, which also drives the second pulley 42 to rotate. The second pulley 42 drives the crushing drum 3 in the middle to rotate for cutting. The first pulley 41 is connected to the second pulley 42 by a belt. The rotation of the first pulley 41 drives the crushing drum 3 in front of the outer cover 2 to rotate. This realizes that the crushing motor 401 drives the three crushing drums 3 to rotate and cut, achieving efficient power transmission.

[0028] In this embodiment, the front end of the outer cover 2 is provided with a baffle 21, and the middle position of the baffle 21 is provided with a feed inlet 211. The upper part of the feed inlet 211 is aligned with the bottom of the crushing roller 3 located on the front side. The rear end of the outer cover 2 is provided with a cleaning port 25 sealed with a door.

[0029] It should be noted that the baffle 21 set at the front end of the outer cover 2 is used to block the wood chips produced by cutting. Since the wood chips produced by cutting are large and have great kinetic energy, they are easy to fly out from the front. Therefore, the baffle 21 can block them. The feed inlet 211 is used to transport wood. The prepared wood is smaller than the feed inlet 211 so that the wood can be crushed by the crushing roller 3 in sequence to complete the wood crushing work.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
